Hello dear native speakers

Is this sentence well-formed?

A suitably experienced guide once recommended that other forms of entertainment such as sailing, hiking, and cycling should not be forgotten as there "IS" wide variety in taste among tourists.

Am I using "is" correctly based on the fact that the verb "recommended" is a past verb?

how about the rest of sentence?

Thanks

Answer

Yes you are using "is" correctly and the sentence is very good. 
"is" in your sentence is not related to "recommended", but to "the wide variety". 
"There is a wide variety OF TASTES among tourists". 
Often In english we have to remember what we or an Author wrote previously so that everything matches and agrees, but we also write and read left to right, so it is just a case of having more experience of knowing when to refer back and when to refer forward. Practice will help.
